Title: Production of anthraquinone intermediate
Inventor: TAKESHITA AKIRA
IPC: C09B1/503
Filed: 1978-09-01
Abstract: PURPOSE: 1-Aminoanthraquinone is converted into the 2,4-dibromo compound in an organic solvent, which is, without isolation, extrated with sulfuric acid and hydrolyzed by adding boric acid to give 1-amino-2-bromo-4-hydroxyanthraquinone.  
     CONSTITUTION: The above objective compound is obtained from 1-aminoanthraquinone without isolation process, in which the first dibromination is effected in an organic solvent insoluble in sulfuric acid as 1,2-dichlorobenzene in the presence  of an acid acceptor as sodium carbonate, then, the product is extracted with sulfuric acid, which is, when necessary, adjusted in concentration, and hydrolyzed with boric acid to give the objective compound.  
     EFFECT: The complicated process of isolating the dibromination product is unnecessary. Since the conversion into the dibrominated product is high, the quality of the product is good and bromine can be used completely.  
     USE: Intermediate of dyes.
